Conservation and variation of cysteine degradation systems in Enterobacteriaceae bacteria. a Genomic context of the genes in the bacterial cysteine degradation systems conserved in bacteria. b Comparison of the genomic contexts of the bacterial cysteine degradation systems among genomes of Enterobacteriaceae bacteria. Representative examples of bacterial genomes are shown. Note that Xenorhabdus bovienii contains yhaO, and some Escherichia coli strains (e.g., CFT073) and Salmonella enterica strains (e.g., CT18) lack yhaO; thus, they represent subgroups. Data were obtained using the web resource STRING (
